Gravel Guides for Colorado Ground, Filed by the Question
Almost everyone who reads these guides is standing in front of a job that has already gone wrong once: a lane that rutted over the winter, a path that washed flat, a patio that rocks underfoot. The guides are filed by the question that brings people here rather than by category, so start with whichever one matches yours.
How deep does a gravel driveway have to be here?
Clay that swells with moisture and frost reaching about 30 to 36 inches through much of the state are what make this question different from the same question anywhere else. The guide works through base depth against surface depth, and why the layer underneath is the one that decides how the drive looks in its third spring.
How much Class 6 does a drive actually take?
Colorado specifies base by CDOT class, and Class 6 is the common driveway and pad base. This one covers how deep to compact it, how lift thickness changes the result, and how to get from a measured area to a tonnage. The product itself is Class 6 Road Base.
Measurements go into the material calculators for a tonnage once the reading is done, and the product range lists the grades the guides name.
